Superlative Arms .875 Adjustable Gas Block – Clamp on – Stainless Steel – Melonite

Unlock cleaner, cooler, and more controlled shooting with the Superlative Arms Patented Bleed Off® Adjustable Gas Block—designed for direct impingement systems on AR-15, AR-10, and LR-308 platforms. Unlike conventional adjustable blocks that restrict gas flow, this innovative system vents excess gas forward, dramatically reducing internal pressure, heat, and carbon buildup.

Whether you’re running suppressed, using a short-barreled rifle (SBR), or simply want to extend the life of your bolt carrier group, this gas block delivers elite-level performance with minimal maintenance. With 30 locked adjustment positions and a patented external detent system, it offers precision tuning without the risk of carbon fouling or screw erosion.

Crafted from 416 stainless steel and finished in corrosion-resistant black Melonite QPQ, this clamp-on block is built for durability, reliability, and performance.

Patented Bleed Off® TechnologyVents excess gas forward, reducing heat, carbon buildup, and blowback for cleaner operation.

30 Locked Adjustment PositionsFront-mounted screw allows precise gas tuning for suppressed or unsuppressed setups.

External Detent SystemAdjustment detent is located outside the block, eliminating contamination and carbon lock-up.

Suppressor & SBR OptimizedBleed Off port exhausts excessive pressure, improving comfort and reliability in short-barreled or suppressed configurations.

No Screw Erosion or SeizingAdjustment screw doesn’t restrict gas flow, preventing wear and ensuring long-term reliability.

Built-In Safety MechanismPrevents accidental removal of the adjustment screw during operation.

Premium ConstructionMade from 416 stainless steel with a black Melonite QPQ finish for corrosion resistance and durability.
